Summary

Glamo3362 is the graphics chip in the Neo FreeRunner. It supports 2D and 3D acceleration, and provides an extra SD interface which is used for the uSD card slot (the other one is used for the Wlan adaptor).

Glamo's 2D engine is currently used to accelerate solid fills and blits in both XGlamo (Kdrive) and X.org (xf86-video-glamo).

The datasheets for the chip are not public, but have been made available (under NDA) to a few community volunteers who are interested in working on accelerated drivers. Please post to the devel mailing list if you are interested in joining in this effort. This mailing list thread has some discussion on the topic.

Hardware Acceleration

This is a compilation of all the publicly available information that is known about the Glamo 3362 used in the Neo FreeRunner GTA02 and links to past and present projects utilizing the Glamo's hardware acceleration. If anyone is working or has worked on hardware acceleration with the Glamo please add any links and any further information to this page.

Timing settings

The CPU (S3C2440) memory bank setting values can be adjusted in such a way that Glamo performance is increased. Bootloader usually takes care of this setup so to change these settings at startup, bootloader with different values can be flashed. Besides flashing bootloader, one can use other tools that can set the memory bank.
